They go to the hotel and are met with an alien on board and scramble back to the elevator and back to Earth. Back at the factory Wonka wants them to help Charlie run the factory but they refuse so he gives them a pill to make them younger but they take to much as Mrs buckets mother becomes so young that she vanishes but Charlie and Wonka go to save her and bring her back.
